LoRaWAN(TM) is the MAC layer defined by LoRa Alliance(TM) over LoRa devices. LoRa is one of Low-Power Wide-Area Network (LPWAN) technology. LoRaWAN networks typically are laid out in a star-of-stars topology in which gateways relay messages between end-devices and a central network server at the backend. Gateways are connected to the network server via standard IP connections while end-devices use single hop LoRa(TM) or FSK communication to one or many gateways. A LoRa network distinguishes between a basic LoRaWAN (named Class A) and optional features (Class B, Class C ...): * Bi-directional end-devices (Class A) * Bi-directional end-devices with scheduled receive slots (Class B) * Bi-directional end-devices with maximal receive slots (Class C) This patch set add LoRaWAN class module implementing the stack, especially the soft MAC, between socket APIs and LoRa device drivers. socket APIs: send and receive the data ------------------------------------------------------------------------ LoRaWAN class module implements soft MAC: append the header/footer, encryption/decryption, timing slot and MAC commands ------------------------------------------------------------------------ LoRa device drivers: send and receive the messages for MAC layer ------------------------------------------------------------------------ LoRa devices This module starts from simple and implements partial Class A end-devices features defined in LoRaWAN(TM) Specification Ver. 1.0.2. More features and complexity, for example regional parameters, confirmed data messages, join request/accept messages for Over-The-Air Activation, MAC commands ... will be added in the future. Besides, I upload these patches and open discussion. For example, the more common/flexible interface for compatible LoRa device drivers and protocols implementation, etc. Another idea mentioned by Andreas: Make PF_LORA and PF_LORAWAN like PF_INET and PF_INET6 exist at the same time. That is also interesting.
